Different Type Of Sandboxes in Salesforce

Developer Sandbox:  Developer sandbox is a copy of production, it copies all application 

and configuration information to the sandbox. This type of sandboxes are limited to

200mb  of test and sample data, which is enough for many development and testing tasks. 

You can refresh type of sandboxes once per day.

Developer Pro Sandbox: Developer Pro sandboxes copy all of your production 

organizations's reports, dashboards, pricebooks, products, apps and customizations under 

setup but exclude all of your organization's standard and custom object records,documents 

and attachments. This type of sandboxes are limited to 1gb of test and sample data. We can 

refresh this type of sandbox once per day.

Partial Data Sandbox: A Partial Data Sandbox is a developer sandbox plus the data you 

define in a Sandbox Template. It includes the reports, dashboards, pricebooks, products, 

apps and customizations(including all of your metadata). Additionally as defined by your 

sandbox template, Partial Data Sandboxes can include your organizations' standard and 

custom object records, documents and attachments upto 5gb of data and a maximum of 

10000 records per selected objects. A Partial sandbox is smaller than a full sandbox and a 

shorter refreshment interval of  5 Days.

 Sandbox Templates allow you to pick specific objects and data to copy to your sandbox, 

so that you can control the size and content of each sandbox. Sandbox templates are 

available only in Partial Data and Full sandboxes.

Full Sandbox: Full copy sandbox are exact copy of Production including standard and 

custom object records, attachments and documents. You can refresh full copy sandbox after 

29 days.
